Toxic and side effects during and after chemoradiotherapy for nasopharyngeal carcinoma seriously affect patients' treatment compliance and long-term quality of life. Active and effective prediction, prevention and management of toxic and side effects is an important element to improve the prognosis of patients. Leucogen has the ability to promote the growth and maturation of granulocytes in the bone marrow and the proliferation of leukocytes, and is widely used in radiation therapy and chemotherapy-induced leukopenia in malignant carcinomas. In addition, leucogen may have potential anticancer synergistic effects. Therefore, based on the application prospect of leucogen in preventing myelosuppression during chemotherapy for solid tumors, the study was designed to investigate the efficacy and safety of leucogen versus placebo on leukocyte and platelet whole-course management assisted by platinum plus low-dose long-term continuous intravenous infused 5-fluorouracil chemotherapy in the treatment of stage IV, recurrent or metastatic nasopharyngeal carcinoma.
≥18 years old and ≤60 years old；
Pathological diagnosis of stage IV, recurrent or distant metastatic nasopharyngeal carcinoma；
Patients with stage IV, metastatic (including primary and secondary) or recurrent nasopharyngeal carcinoma who are not suitable for local treatment, local treatment mainly refers to measures related to anti-tumor therapy, including surgery, radiofrequency ablation, transhepatic artery chemoembolization (TACE), radiotherapy (excluding bone metastases, local moderate amount of radiation therapy for symptom relief without affecting hematological indicators)；
Karnofsky functional status score should be at least 70 points (the decline of functional status score caused by tumor should be appropriately relaxed after the judgment of the researcher, and the minimum score should be no less than 50 points. );
Have a history of allergy to 5-FU, cisplatin and leucogen;
Received elevated blood therapy 14 days prior to screening (including cytokines, leuk-lifting drugs, platelet-lifting drugs, anemia-correcting drugs, etc.)
Major surgery other than nasopharyngeal cancer was diagnosed within 28 days prior to randomization or major surgery was expected during the study period;
The subject has any active autoimmune disease or a history of autoimmune disease (e.g., but not limited to: interstitial pneumonia, uveitis, enteritis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism); Subjects with vitiligo or asthma in complete remission during childhood without any intervention as adults could be included; Subjects with asthma requiring medical intervention with bronchodilators were excluded);
